SPECIFICATION forming part Of Letters Patent N 0. 658,17 6, datedSeptember 18, 1900. Application filed May 8, 1899. Serial No. 715,952.r(No model.)

To all whom t may concern..-

Be it known that I, EDWARD P. HOLDEN, a citizen of the United States,residing at Chicago, county of Cook, State of Illinois, have invented acertain new an'd useful Improvement in Can-Soldering Machines; and Ideclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to Whichitpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention has for its object the production of a solderingmachine of.that class known as floating soldering-machines that is, a machinewherein the can is pushed or rolled through the successive operationsnecessary to solder the ends onto the body.

In the drawings, Figures 1, 2, and 3, coupled together, represent a sideelevation of the entire machine. Fig. 4 is a vertical section on theline 4 tof Fig. 1. Fig. 5 is a vertical section on the line 5 of Fig. 2.Fig. 6 is a horizontal section looking from above on the line 6 6 ofFig. 2. Fig. 7 is an enlarged cross-section of the soldering-vat on theline 7 7 of Fig. 6. Fig. 8 is an enlarged detail of 'the rack-bar. l

In carrying out the invention, A,A,A2,A3, and A4 represent suitablecarryingframes or arches, preferably made of VT-iron, as shown. Fromthese arches or frames the various parts of the machine are sustained.

.Iournaled in suitable brackets A5, extending from the frame A, is ashaft B, carrying a sprocket-wheel B. On the saine shaft B is agear-wheel B2,and meshing therewith is a pinion B3 on a counter-shaft,the latter also carrying ,the band-wheel B4,which drives the machine. Onthe opposite end of the machine and journaled in the bracketsBi, Fig. 3,is another shaft B6, carrying another sprocketwheel B2. Passing aroundthese two sprocket- Wheels B and B7 is a sprocket-chain made up incross-section substantially as shown in Figs. 4 and 5, each linkconsisting of a main portion C, with antifriction-wheels C' and ahorizontally projecting arm C2. Journaled on the arm C2, so as toreadily revolve, is a sleeve carrying a roller Caandapinion C4,and atcertain points in the operation the pinion 5 and 7.

C4 on the arm C2 engages with `the rack bar C5, and thus revolves theroller C2. The several links are pivoted together, so that when thesprocket-wheel B' is revolved the entire conveying apparatus moves.

In order that the invention may be clearly understood, I will describethe movements of the can and describe-the mechanism in detail as eachparticular set is reached.

Referring to Fig. 1, the-can is fed through a chute D into thev machinebetween two of the arms C2 of the chain. It rolls down the strip DJ tothe. iuxing-vat E. This vat is shown in detail in Fig. 4. It is made upof a piece of angle-iron E,.having a groove E2. The edge of the canrolls in this piece of angle-iron, with the seam between the canbodyandcan end rolling in the groove E2. .The other end of the can issupported by the strips E2 E4. Supported by the bracket E5, Fig. 1, is avessel E6,containing the liquid flux. A ,pipe E7, controlled by a valveE2, leads therefrom down to a point below the strip E and up4 throughthe bottom of the same, so thatithe flux is fed in the groove E2. At apoint adjacent to theend of the flux- Vvat E and underneath the same isanother receptacle E9, with an orifice in the bottom of thel vat E, sothat the flux can drop back into .the-'receptacle E9. The end of the vatE beyond the orifice is inclined upward slightly, as shown at E10, Fig.1, so that any flux carried beyond by they rolling can will run back.The can now reaches the solder-vat F, Fig. 2. This vat is shown incross-section in Figs. There is the receptacle proper, F', Fig. 7with astrip F2 bolted thereto to receive and support4 theend of the can, thisstrip having a downward projection f, which extends into the solder.This strip is adjustable horizontally. On the vat proper is anotherprojectionf, which supports the side ofthe can immediately above theseam to be soldered. It willbe observed by reference to Fig. 7 that theprojection f extends down into the solder-bath and protects the entireend of the can. Between the point of the projection fand the face of theprojection f is thus left a small space, which is lilled with a bead ofthe solder. As thecan rolls along, the seam between the body and the endof the can rides in this beadiof solder andpicksil up the desiredquantity. The upper endio'f the can is supported by the strips F3 F4,Fig. 5.

Referring again to Fgs. 6 and 7, it will be observed that the solder-vatat one point is e of the rod G4, pivoted to the arm G5, and eccentrically pivoted to the disk G6 on the shaft 13, so that as the shaftB revolveslthe rod G' is reciprocated and tilts theidi'pper G, and thelatter `picks up thesoldermin` the `vat F5 and allows it torunintothevatF. An orifice f2 throughthelpartitionf8 maintains the solder in thevatF' at eX-actly In order that the solder;`

the height desired.

may iiow` freely and not bank up or clog the orice f2, I provide acopperor soft-metalV tube coated with tin, so that the solder passesythrough a tinned surface. i As the can rollsl along through the vat Fthe seam between the` can-body and the can end rides in the solder," asshown in Fig. 7, and picks up a beadotiity as previously described. YThe solder-vat is of i course heated from any suitable source-f-as'glfor instance, by the burners F6, Fig; `2. When-r the can reaches the endof the soldervat,the

strip F3 is turned up, as shown at F7, Fig. 2, i and throws the `cantothe verticalvposition and onto the plate H. Thisplate is perforated The1and suitably heated from the pipe H'. hot-air comes up throughthe-"orifices'inthe plate H and melting the solder that has adhered tothe seamcauses thesolderto run` into the seam and iill the same.` Thecan is then pushed along on end until it reachesith e end of the plate Hand thenceA along-a suit` able slide until it reaches thesprocket-wheelIt then rides between the strips .I J andv B7. is carried aroundthesprocket-wheel. This action of course reversesthe position of the canandbrings the unsoldered end beneath The guiding-strips thentilt thecanto bring the seam in the proper position.` The can is then Icarriedthrough exactly thelsame operaL tiousas thoseijust described, andwheniit reaches the end of the `machine adjacent to the sprocket-wheel Bboth ends have been effectively soldered. The ,can is then `dischargedthrough the chute lK.

Suitably sustained from the main frame of the machine in the path of thepinions C4 is a rack-bar M. This rack-bar is located adjacent to theiiuXing-vatsand also adjacent to the soldering-vats. As the can ispushed alongand reaches the rack-bars the pinion engages therewith, andthe roller C3 is thus revolved and bearing against the side of the canallows it to revolve the can and prevents the latter from sliding ratherthan rolling.

. What-I claimisl. In a can-soldering machine a fluXing-vat made up'ofapie'ceof'augle-iron in which the end of the can rolls, a groove in thebottom oi' said vat, a receptacle-*above the vat with meansAfoiradniittingia continuous `stream of` fluxintothe vatand a receptacleto .receive theux at the'discha'rge end of the Vat, substantially asdescribed.

2.
